A trie is a data structure for efficiently storing and retrieving strings with identical prefixes, like "meet" and "meek".
-
Add the dependency to your
shard.yml
:dependencies: cadmium_trie: github: cadmiumcr/trie
-
Run
shards install
require "trie"
trie = Cadmium.trie.new
trie.add("meet")
trie.size
# => 5
trie.add("meek")
trie.size
# => 6
trie.contains?("meet")
# => true
trie.find_prefix("meeting")
# => {"meet", "ing"}
trie.find_prefix("meet")
# => {"meet", ""}
trie.find_prefix("me")
# => {nil, "me"}
trie.keys_with_prefix("me")
# => ["meet", "meek"]
trie.add(["m", "me"])
trie.matches_on_path("meeting")
# => ["m", "me", "meet"]
